Lyon,- inFrance, have invented a certain new andusefulCarbureter, of whlch the following "-isaspeeifieation.

This invention relates to carburetors for nii-xing'i vaporizable petroleum spirit or the like with" air for the a imentation of explosion en'gnies'-.- I i The lcar bureter which forms the object of the present invention is shown in vertical section in the annexed drawing.

A is a crown or cap screw-threaded at A forming a tubular connection and its flange A is internally screw-threaded to engage similar threads on a cylinder B in which is formed a valve seat 13 closed by a valve C. The stem C of the latter is guided in its movements by a guide D carried by a perforated s ider l) mounted on a shoulder B in the cylinder B and forming one member of a throttle the other member of which is formed by a erforated disk Y having a flange Y rotatably mounted in the upper part of the cylinder B and operatable by a pro ecting arm X passed through a slot 13' in the cylinder B. The tubular downward prolongation B" of the cylinder B is internally screw-threaded at B to engage threads on the hollow c linder J within which a hollow cylinder E sli es forming means for automatically controlling an additional supply of air. The'cylinder E is pierced with 0 enings E preferably having the shape of triangles of which the base is at the to and its base E is formed with openings it. The cylinder J is also pierced with openings .1. A jacket F has its upper edge bent. inwardly at F toengage over a B of the cylinder B. The jacket F extends downwardly inclosing a space surrounding the cylinder J, and is shouldered outwardly at F and at its lower end it is carried out wardly at F and downwardly at F, and is bolted by bolts Q and nuts U to the flange (l of a second jacket G pierced with holes G for the passage of air, and forming in its lower art the float chamber of the carburetor.

Between the flanges F G are" two plates H, O the lower plate having a central orifice O and the upper )late being perforated at H and Id to form t e fixed member of an adjustable throttle of which the movable por tion consists of a cylindrically flanged perforated plate I rotatably mounted in the acket Specification of Letters Patent.

CARBURETER.

F below the shoulder F and provided with an arm I extending through a slot F in'the jacket F.

The passage of carbureted air is regulated by the throttle formed by theiplates H, and

I, of which the position is regulated from outside by means of the arm. 1

Between the flange F of jacket F and the air holes G of jacket G is arranged a supplementary envelop K brazed to the lower jacket and forming an annular passage for v the air.

The jacket G is shouldered at G below the air holes G; and again at G and its base narrows to a conical flange G in which is fitted the body V in which the valve seat V is formed against which the valve V bears upwardly. float l which is preferably of cork. On the shoulder G is closely fitted a plate G having a central orifice G for passage of the valve stem V On the plate G is supported a plate G which is flared conically at G and thence carried horizontally outward at G. G are air holes in part G The supply of essence to the carburization chamberis effected by capillarity, by means of short rods of ratan N carried by tubes M passing from orifices in plate Gito orll es in plate G The jacket G is internally lined with a cylindrical piece of felt U which conducts the spirit to the ratan rods N by which the spirit is conveyed by capillarity to the annula-r felt plate Z. Above the plate Z is a felt plate L perforated at L and perforated plate W of metal. The valve C is normally held on its seat by a spring S, and the s )ring Valve E is normally pressed downwards y a spring R surrounding a fixed stem T.

F are air holes in jacket F.

It will be seen that the suction of the engine which is connected to cap A draws air.

The stem V of valve V carries the in at holes G G into the space above plate G. It passes through the felt plate L which is kept down in place by the metal plate VJ and takes up the spirit supplied to said late by the ring Z to which the spirit has .een supplied by carpillarity thrmigh the numerous capillary )assagesin the ratan N supplied by the fe t G which is immersed in the spirit in the float chamber.

The shape of plate 0 prevents direct current of air acting on the felt ring Z. Additional air enters by the holes F and H. The carburized air passes up through holes H and E lifts valve 0 and passes through the holes in the plates 1). tie I the maximum richness of carburization is given; by opening it the quantity of spirit and consequently the richness of carburization are reduced; at low speed the valve E is barely lifted and admits at IE only the additional air required for normal carburization for low speed. On advancing the i nition the aspirations become more foreib e and tend to increase the quantity of spirit sucked in, but at the same time the valve E rises more and allows a greater quantity of pure air to pass, so that the mixture may be either automatically reestablished as at low speed, or diminished in richness according to the setting of spring R. v

The arm X of the throttle Y is intended to I be ermanently fixed according to the power of t e motor to be actuated.

What we claim as our invention'and desire to secure by Letters Patent of the United States is 1. In a carburete'i" thecombination with a carbureting chamber and a spirit supply chamber, of pieces of ratan for conducting By closing the throt-' the spirit from the latter to'the former by capillaryiil action and a feltjfsupplier in contact with the ratan in the spirit supply chamber. I p

2. In a carbureter the combination of a valve body, a suction valve therein, a throttle above the suction valve, a spring controlled extra air inlet valve below the suction valve, a mixture chamber With uncontrolled air inlets below the extra air inlet valve, a float chamber below the mixture chamber, and a throttle between the mixture chamber and extra air inlet valve operative to control the passage between said mixture chamber and suction valve and also to congrol additional air inlets to the mixture chamer. a

In witness whereof we have signed this specification in the presence of two witnesses.
